A/C makes rattling noice when compressor is on

I have talked to several mechanics on the phone here locally and they all want to change out the whole ac system. Sounds like a bit much but then they aren't looking at the car just assuming I'm saying its the ac clutch or compressor. Also they say the clutch isn't separate anymore so you have to change out everything. So I'm taking it into one of the shops to have it checked out before I do anything else. Does anyone know if thats correct - clutch and compressor are not separate they have to be changed out as one item and consequently everything has to be changed.A/C makes rattling noice when compressor is on
